' REVEFiSlNG-GEAR. 7

versing-Gear; and. I do hereby declare the 1 following to be a full, clear, and exact description of-the invention, such as will enableothers skilled in the art to which it appertains to make and use the same. y

This invention relates to reversing-gear for altering the direction of revolution of a driving-shaft, more particularly in an icecutting machine and it consists in the novel construction and combination of the parts hereinafter fully described and claimed. In the drawings, Figure 1 is a longitudinal section throu h the drlving mechanism. Fig. 2 is a plan view of the. driving mechanism. Fig. 3 is an end view of the driving mechanism. Fig. 4 is a cross section taken on line min Fig. 1. Fig. 5 is a detail front view of the operating-arms. Fig. 6 is a modification. A is the motor-shaft, or other equivalent shaft, which is driven by any suitable motor, Whether directly or indirectly.

B is the driving-shaft, which is driven in opposite directions from the shaft A by means of suitable gearlng and-clutch mechanism. These two shafts are, journaled ,in bearings of any ap roved construction, which are not shown in t e drawings.

C and C are two similar beveled toothed wheels, which are mounted loose upon the shaft A, and B is a beveled toothed wheel which is secured on the shaft'B and which gears into the two wheels. 0 and C. The Wheel 0 has a proj ecting hub E, provided with a circumferential groove and the wheel C has a projecting hub E, provided with a circumferential groove 6.

F is a coupling-block formed of two similar.

halves, which separate longitudinally and are secured together by bolts f. Theblock F has projections g, which en age with the grooves e and e of the said hu s, and g is a bolt or pin which dpasses through the halves of the block F an through the shaft A and prevents the block F from either revolving or sliding longitudinally upon the said shaft. The wheel. C has also a circular chamber H formed in its back, and this chamber is provided With a lip or flange h. The wheel C in a similar manner is provided with a circular chamber H, having a flange h. The chamber of each wheel forms a friction clutch I Specification of Letters Patent.

member. Each chamber is provided with a split s ring-ring I, which forms the other friction 0 utch member.

Two disks J and J splined to the shaft A, and these disks slide within the rings I. The disk J is provided '1 with a hub having a circumferential groove y', and the disk J is provided with a hub having a circumferentialgroove y". Each disk J and 'J has a wedge K secured to its periphery and projecting between the'ends of the s lit 1 sprm -r1n to Whichit ertains,and this We e is pre erab ydovetaile so as to force the en s of the ring outward atthe same time as it presses them apart. Eachring isarrangedin one of the chambers ,and the lip or flange of the chamber prevents it from sliding longitudi nally. The clutches are thrown into and out of engagement by sliding the disks J and J longitudinally u on the shaft A. When either disk is move toward the wheel to which it pertains, the wedge secured to it expands the s lit spring-ring and forces it into frictional d iving contact With the eriphery of its chamber. hers are operated and M, each of which is formed of two longitudinal halves, which are secured to ether bybolts mand m. The arms M have a l orked jaw N at one end, have a similar forked jaw N.

P is a collar formed in two longitudinal halves secured together by bolts and jour-- naled in the groove 3' of the disk J. The collar P has projecting pivots p, by means of which it is pivoted in, the jaw N.

P is a collar also formed in longitudinal halves secured together by bolts. The collar P is journaled in the groove 1" of the disk J, and it has projecting pivots p, which engage with the jaw N. I

R is a plate or bar secured to the adjacent end portions. of the operating-arms M-and M, and s is a double eye at the middle part of The clutch mem ing-lever or other approved operating evice. The clutches are operated when the bar R is slid longitudinally, as hereinbefore described, and when the clutches are placed in an intermediate position, as shown in the drawings, the s lit spring-rings are revolved in their chain ers and do not revolve the toothed wheels.

In the modification shown in Fig. 6 the inof ring-segments I, and the disks J or or both of them, are provided with a plurallty of are provided and are 'IIO' wedges K similar to the wedges K, and arranged between the ends of the ring-segments I.

What I claim is 1. The combination, with a shaft, and two wheels mounted loosely thereon and provided with hubs having circumferential grooves; of a block secured to the said shaft between the said wheels and provided with projections which engage with the said" said grooves, means for securing the said block-sections to the said shaft, and clutch mechanism for connecting the said wheels alternately with the said shaft.

4. The combination, with a shaft, and two wheels mounted loosely thereon and provided with clutch members and hubs having circumferential grooves; of a block secured to the said shaft and provided with projections which engage with the said grooves, slidable clutch members splined to the said shaft and provided with circumferential grooves, collars arranged in the grooves of the said clutch members, operating-arms pivoted to the said collars, said arms being formed of longitudinal arm-sections, and an operating-bar connecting together the adj acent end portions of the said arms.

In testimony whereof I allix my signature in presence of two witnesses.
